Managing Voltage Variation


Engineers make many tradeoffs when designing SoC’s to better meet design specifications. Power, Performance and Area (PPA) are the primary goals and all three impact the cost of the implementation. For example, higher power and performance can both require more expensive packaging for power and signal integrity as well as cooling. The larger the die area the fewer die per wafer which drives u... » read more

Blog Review: Aug. 2


Siemens' Katie Tormala points to the need for die attach thermal testing to ensure efficient removal of heat dissipation from power electronics components to prevent premature failure or thermal runaway. Synopsys's Dermott Lynch notes that over 30% of semiconductor failures are attributed to electrostatic discharge, with damage ranging from leakages and shorts to junction and metallization b... » read more

Battling Over Shrinking Physical Margin In Chips


Smaller process nodes, coupled with a continual quest to add more features into designs, are forcing chipmakers and systems companies to choose which design and manufacturing groups have access to a shrinking pool of technology margin. In the past margin largely was split between the foundries, which imposed highly restrictive design rules (RDRs) to compensate for uncertainties in new proces... » read more

Week In Review: Design, Low Power


Arm is helping to address the ongoing talent shortage through its newly announced Semiconductor Education Alliance, with a long list of partners, including Arduino, Cadence, Cornell University, Semiconductor Research Corp., STMicroelectronics,Synopsys, Taiwan Semiconductor Research Institute, the All-India Council for Technical Education, and the University of Southampton. The Alliance... » read more

Large-Scale Integration’s Future Depends On Modeling


VLSI is a term that conjures up images of a college textbook, but some of the concepts included in very large-scale integration remain relevant and continue to evolve, while others have fallen by the wayside. The portion of VLSI that remains most relevant for semiconductor industry is "integration," which is pushing well beyond the edges of a monolithic planar chip. But that expansion also i... » read more

Blog Review: July 26


Siemens' Chris Spear shows how to make a group of specialized classes in SystemVerilog. Synopsys' Guy Cortez and Randy Fish consider what a silicon lifecycle management strategy looks like for SoCs deployed in HPC and data center environments. Cadence's Veena Parthan provides a primer on writing Python scripts for Fidelity, including API descriptions and different sets of packages to acce... » read more

Week In Review: Design, Low Power


Cadence will acquire Rambus' SerDes and memory interface PHY IP business. Rambus will retain its digital IP business, including memory and interface controllers and security IP. “With this transaction, we will increase our focus on market-leading digital IP and chips and expand our roadmap of novel memory solutions to support the continued evolution of the data center and AI,” said Sean Fan... » read more

Improving Performance And Lowering Power In Automotive


Automotive OEMs are boosting their investments across the semiconductor ecosystem as stepping stones toward electrification and autonomy, and they are starting to encounter some of the same issues chipmakers have been wrestling with at advanced nodes — massive compute performance, thermal and power issues, reliability over extended lifetimes, and a highly diverse and geographically distribute... » read more

Getting Rid Of Heat In Chips


Power consumed by semiconductors creates heat, which must be removed from the device, but how to do this efficiently is a growing challenge. Heat is the waste product of semiconductors. It is produced when power is dissipated in devices and along wires. Power is consumed when devices switch, meaning that it is dependent upon activity, and that power is constantly being wasted by imperfect de... » read more

Mitigating Electromigration In Chip Design


From smartphones to laptops, we use a variety of devices every day that rely on integrated circuits (ICs), or chips, to function. These chips are made up of thousands of transistors and interconnects, which transmit electrical signals from one part of the chip to another. But as demand for speed and complexity forces more energy through ever-smaller devices, this concentrated current flow can t... » read more
